Complete Set Guarantee

Every set is weight-checked

Every set is weight-checked and checked using a visual AI tool before it reaches your table. If a piece is missing, your next hour is free.

  • Each tub has its own QR code and a verified golden weight in grams.
  • Hosts re-check kits after every build, so the next table starts complete.
  • Our visual AI tool double-checks the contents of every kit.
  • Missing a piece? Tell your host and your next hour is on us.
